The V6 SS Opamps are used in place of the original Burr-Brown OPA627 in the CDP. They bring out more music, more depth, and better tonal qualities.
I had to “modify” the CDP case top (with a hole!) to fit the V^ in (on extenders) but had to run the V6 (on extenders, the only way they fit in the CDP) for a week to determine if they were worth the effort. THEY ARE! Ryan at Burson was quite helpful with his guidance.
